IBRIGATING OR BITCHING PLOW.

Speeification of Letters Patent.

Application filed March 20. 1907. Serial No. 363.415.

`constructed or for cultivating between the rows of corn,

potatoes, etc;

A further object is to provide a construction which will enable a plow to have a knife attached thereto for cutting away the roots of weeds and similar growth be- ]t-Ween the rows when the device is used as a cultivator.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of' reference .ndicate corresponding parts in Figure 1 is a side elevation of a plow constructed according to m yqinvention; Fig. 2 is a plan of the plow; Fig. 3 is a rear elevationjFig. 4 is a plan of'two knives which are adapted to be attached to the plow, as will appear hereinafter; and Fig. 5 is a rear elevation of the plow, representing the same with 4the knives attached;

the upperportion of the plow in this view is broken away. i Y

Referring more particularly to the parts, 1 represents a platform of substantially triangular form, presenting side frames 2 formed of angle iron, as indicated, which converge toward the forward extremity of the plow as shown in Fig. 2. Thisplatform 1 is formed of planks Which are laid transversely upon battens 3 which lie upon the flanges 4 of the angle irons 2 as shown in Fig. 3. Extending longitudinally of the platform on the under s'de thereof there is provided a keel orrudder ,consisting of a stouttimber, the sides of which converge downwardly, as indicated. The platform 1 is adapted to be drawn along by a horse or other draft animal. At the forward end of the platform thills 6 are provided,

consisting of flat bars of iron curved as shown in Fig. 1;

the rear extremities of the thills being attached to the side frames 2 of the Aplatform by means of a through-bolt 7, as shown mst clearly in Fig. 2.

The forward portions of the thills 6 are formed with parallel tongues 8 which lie a short distance apart, and between these tongues near the rear portions thereof a 'plow-arm 9 is pivotally attached on a suitable bolt 10.

This ploW-arm is curved, as indicatcd in Fig. 1, and its lower end is provided with a removable hoe 11 which is I adapted to dig into the earth as the plow is advanced.

At a suitable point near the rear of the arm 9, the same is provided with a rearwardly extending lever 12. This lever is provided with a locking mechanism 13 c'ooperating with a segment 14, which segment is attached at its lower end by means of a bolt 15 to the upper side of the platform near the central portion'thereof. The upper end of the segment 14 is connected with the thills 6 by suitable diagonal braces or links 16. In this way the thills and the segment are connected to form a rigid structure. I

In connection with the locking mechanism 13 for the lever 12 I provide a finger lever 17 which enables the lockingbolt 18 to be disengaged from the notches 19 of the segment. It slould be understood that the plowarin 9 has a free pivotal movemcnt on the bolt 10, so that by raising or lowering the lever 12, the elevation of the hoe 11 with respect to the ground levcl, may be changed as desired. Between the tongues 8 forward of the bolt 10 a similar pivot bolt 20 is provided upon which there pivotally attached a clevis 21. The forward extremity of this clevis is formed into a short arc or bow 22 provided with a plurality of openings 23. I have illustratcd this bow with three openings, through any one of which a fastcning bolt 24 may pass near the forward ends of the tongues, and this bow affords means for securcly holding the clevis, as will be readily understood. The forward extrcmity of the clevis is formed into an eye 25 to which a whliletree may be' attached. lf it is dcsired to hold the eye 25 in a more elevated position, the clevis is adjusted upwardly so that the bolt 24 Inay be passed through the lowermost of the openings 23, and vice vcrsa.

In order to adapt the device to be used as a Weed cutter or cultivator between rows of corn or similar crops, I provide knives 26 as illustrated in Fig. 4; the outer edges of the said knives being beveled. These knives are attached to the under faces of the angle irons 2 as shown in Fig. and the cutting edges of the knives project beyond the outer faces of the irons. The keel or rudder 5 runs in the furrow made by the hoe 11 and the bottom' of the platform slides on the ground as the implement is drawn along.

In order to hold the thills securely, I provide side braces or diagonals 27 which attach to the thills at the same points as the braces 16, and these are attached by bolts 28 to the upper side of the platform.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a plow of the class described, in combination, a subslantially trangular platform adapted to rest upon the earth, a hoe mounted forwardly thereof and adapted to form a furrow before said platform, and a keel on the under sideof said platform, extending longitudlnally thereof and running in the furrow formed by said hoe.
